A stretchable Li4Ti5O12 anode and a LiFePO4 cathode with 80% stretchability are prepared using 3D interconnected porous polydimethylsiloxane sponge based on sugar cubes. 82% 91% capacity retention for achieved after 500 stretch–release cycles. Slight decay of 6% in the battery electrode stretched state is observed. As service to our authors readers, this journal provides supporting information supplied by authors.
